Description

A motorised rotating base for your moon/Jupiter or other globe lamp.

It's compatible with Tom Fullen's SVS NASA Moon Globe and RynosaurusRex's Jupiter (printed at 150%) or any other globe model provided the opening at the bottom is between 60mm and 110mm.

I also have a version without a motor (you can rotate by hand) which you can find here.

The model is designed around the readily available tiny but strong N20 motor which is found on eBay or AliExpress. These motors run between 3-12v and are available with various gearbox configurations to suit the required RPM of the project. This model is based on the 30RPM@6V gearbox which drives a 110 tooth bevel gear with an 8 tooth pinion gear. This results in approximately 2 rotations of the globe per minute when running at 5v.

The speed can also be controlled by the potentiometer which drops the voltage and RPM - on the lowest setting it's near silent and very slow moving.

This is sped up, but it could go this fast if you use a faster RPM motor

PARTS LIST

Bambu LED lamp Kit (From Bambu Store, or AliExpress)
N20 micro motor (I used the 30RPM@6v version AliExpress)
Potentiometer / speed controller (AliExpress)
4 short lengths of wire
Soldering iron and solder

ASSEMBLY

See GIF below for basic instructions

WIRING

The wiring is pretty straightforward thanks to the potentiometer and the LED puck which has 5v and ground pads available.

Double check the potentiometer wire order as yours may differ to mine.

The LED USB cable neatly clips into the underside of the base.

put it as remix , and link the charging board also

@nadnerb33

Nice one! are those tiny bearings around the edge of the base?

@iamwhoiam

Yes. They are tiny bearings. But I found that this does not reduce the noise, the noise comes almost entirely from the gearbox of the N20 motor. So in the new version I removed them. I just started to experiment with mechanical design, I will post my remix later.

The motor and its vibrations turned out too loud for me. So I don't use it, but all parts seem to work fine.

some lube will help

Your gears seem to be reversed

@schiko

Replying to @iamwhoiam :

The motor itself was too loud. I tried different things to reduce the vibrations. One thing was to turn the gear.

ein super cooles Projekt! sieht wirklich klasse aus und täuschend echt. nur leider ist der Motor sehr laut... und ich hätte die kabelführung nicht direkt am Controller gemacht, sondern nach hinten

Little too loud

If you go through the trouble of printing the moonglobe, you really should go the extra mile and print the base, and add light and the motor. This adds so much to the already stunning globe. Great work!

@seregasher

does not work. the model is unfinished. how to attach the moon to this? no way. How is the circle supposed to rotate if it is not pressed against the bottom with the motor? no way. The gear slips and the lamp cannot be connected.

@nadnerb33

sounds like you've not assembled correctly, can you post a photo. The moon just sits on top, no fixings required

@tyler.lemmert

check that the capacitor on the potentiometer is not rubbing against the teeth of the top plate. This just happened to me and caused the gear to slip. Once I moved it out of the way, it all worked fine.

@QiuT

I am confused about that if the moon ratates around the base for multiple cycles,wouldn't its LED power cord also rotate with it? If so,could this potentially result in the power cord twisting itself?

(Edited)

The designer has replied

@nadnerb33

The LED and cable do not rotate. The base rotates around the central column with the cable running through the middle. The only part that moves is the "lid" with the teeth.

@QiuT

Replying to @nadnerb33 :

I see. So that’s a very clever design to avoid this situation !

@philadkins

All in all, a nice print. Certainly adds to the over all look of the Moon globe. It's a bit fiddley to assemble if you have big fat fingers and I had issues with cable management, the slots were a bit too small for the cable that was on my puck. I found that I had to put a couple of rubber baby buggy bumpers on the bottom to let the unit sit flat. On the plus side, this also cut the motor sound a bit as well.

Really well thought out and designed.
